Sori in ovaries, black, at first compact. 



Spore-balls forming indefinite masses, varying in number of spores, 

 but generally large. 



Spores smootli, generally globose, sometimes shortly ellipsoid, 

 yellowish-brown to dark-brown, 9-11 ^t diam. or 9-12 x 7-8 /n

 The spores cohere well, but in the process of mounting for the microscope 

 they break up into packets of various sizes.

TOLYPOSPORIUM Wor. 



Sori in various parts of the host, but mostly in the ovaries, and forming 

 a granular spore mass at muturity. 



Spore-balls dark-coloured, composed of numerous spores permanently 

 united. 



Spores bound together by ridged folds or thickenings. 



G-ermination similar to that of Ustilago. 



The characteristics of this genus are the very firm spore-balls and the 

 union of the individual spores by ridged folds or thickenings of their outer coats. 



It is distinguished from Thecaphora by the dark-coloured spore-balls 

 and the spores being inseparably united.
